BACKGROUND OF THE INVENTION Fluid dispensing containers, such as for containing beer, other carbonated beverages, and'the like, have been provided for home use wherein the charging propellant for providing a dispensing force on the fluid within the container construction is either internally supplied or externally supplied.

Such container constructions generally have a cylindrical configuration dictated not only by manufacturing expedients,'but also by esthetic considerations.

It has been found, according to the teachings of this invention, that some means should be provided for conveniently supporting such a dispensing container in its dispensing position in a refrigerator or the like as well as provide means for readily stacking such container constructions for transportation purposes and the like.

In addition, it has been found, according to the teachings of this invention, that a convenient means must be provided for the consumer to attach an external propellant supply source to the container construction.

SUMMARY This invention provides an improved container construction that solves the aforementioned problems.

In particular, the fluid dispensing container construction of this invention has a substantially cylindrical container body provided with opposed ends one of which has a dispensing unit projecting therefrom for dispensing fluid from the container body. An annular collar of this invention is carried by the container body and projects beyond the dispensing unit thereof to tend to protect the dispensing unit thereof, such collar additionally providing handle means for facilitating the carrying of the container construction, means for engaging against a supporting structure to prevent rolling of the container construction, a fluid drip trap for the dispensing unit and means for facilitating the stacking of like container constructions.

For example, the non-dispensing end of a like container construction can be vertically supported in telescoping relation into the collar of a container construction below the same in a stack thereof with such collar preventing the upper container from engaging the dispensing unit of the next adjacent lower container construction.

The dispensing unit for the container construction of this invention can carry a needle-like tubular member having a passage therein which is provided with an inlet externally located relative to the container body and an outlet located in fluid communication with the chamber of the container body by means of a one-way check valve so that a valve unit of an outlet member of an external propellant source can be attached in a guided, needle insertion manner to the container construction of this invention to charge the fluid containing chamber with a suitable propellant passing through such needlelike member.

Other details, uses and advantages of this invention will become apparent as the following description of the present preferred embodiments thereof in the accompanying drawings proceeds.

DESCRIPTION OF ILLUSTRATED EMBODIMENTS Referring now to FIGS. 1,2 and 3, an improved fluid dispensing container construction of this invention is generally indicated by the reference numeral 10 and comprises a container body 11 having a generally, cylindrically shaped side wall means 12 provided with an outwardly directed convex front end wall 13 and a concave rear end wall 14 suitably shaped so as to be inwardly necked at 15 to define an annular shoulder 16 in the side wall means 12 and formed with a central arcuate recess 17 therein. Such container body 11 defines a fluid receiving chamber 18 therein which can be placed under pressure by a suitable propellant, such as CO also disposed within the chamber 18 and acting directly on the fluid, such as beer, a carbonated beverage, and the like, disposed in the chamber 18 to force the same up a syphon and/or anti-foam tube 19 at the inlet end 20 thereof and out through an external spigot 21 that is opened and closed by a handle means 22 in a manner well known in the art whereby the fluid dispensing container 10 can be utilized to manually dispense desired quantities of fluid therefrom.

The spigot 21 and syphon tube 19 are carried by a plate structure 23 adapted to have a first portion 24 thereof inserted through a circular opening 25 formed in the center of the front wall 13 and be locked in place by a plurality of tongues 26 on the: portion 24 being rotated so as to be disposed against the inside surface 27 of the front wall 13 in a camming manner after such tongues 26 have passed through complementary slots 28, FIG. 7, in the front end wall 13 and then rotated out of register therewith as illustrated in FIG. 7. The front portion 29 of the'plate 23 carries an annular sealing gasket 30 held thereto by a retaining ring 30', the gasket 30 being adapted to be compressed in an annular groove 31 formed in the front wall 13 outboard of the opening 25 thereof so as to fluidly seal the plate 23 thereto when tongues 26 have been locked in place as illustrated in FIG. 7.

Thus, the spigot 21, plate 23 and syphon tube 19 define a dispensing unit 32 for the container construction 10 of this invention.

As illustrated in FIG. 4, an opening 33 passes through the plate 23 of its dispensing unit 32 adjacent the spigot 21 and receives a fluid level, sight indicator 34 which, when covered by liquid in the chamber 18 when the dispensing unit 10 is disposed in the position illustrated in FIG. 3, indicates to the user that the dispensing container 10 is at least half full of liquid. However, when the liquid level in the chamber 18 falls below the indicator 34, the indicator 34 diffuses light in such a manner that the same appears to be lit up so that the user knows that the dispensing container is now less than half full and it is time to be considering the ordering of a new dispensing container 10.

The plate 23 of the dispensing unit 32 also has a stepped bore 35 on the other side of the spigot construction 21 from the indicator 34 with the stepped bore 35 defining an annular shoulder 36 within the plate 23 as illustrated in FIG. 4. A needle-like, tubular member 37 is carried by a cylindrical retainer 38 that is press fitted into the larger section 39 of the stepped bore 35 so as to position an open end 40 of the tubular member 37 within the chamber 18 and an outer closed end of the needle-like member 37 externally of the container body 11 but within the larger portion 39 of stepped bore 35 so that such projecting part of the needle-like member 35 is protected within the stepped bore 35 as illustrated.

An encasing, flexible one-way valve member 42 has an annular flange means 43 disposed between the retainer 38 and the shoulder 36 of the stepped bore 35 while the remaining portion 44 thereof projects through the reduced part 45 of the stepped bore 35 and extends beyond the end 40 of the needle-like member 37, the member 42 having an opening 46 therein which surrounds the needle-like member 37 and is adapted to be interconnected through opposed slits 47 formed in the side thereof to the chamber 18 of the container body 11 when a fluid pressure in the opening 46 is greater than the fluid pressure in the chamber 18. However, even though the slits 47 are located adjacent, but spaced from the end 40 of the needle-like member 37 so that propellant passing through the passage 48 of the needle-like member 37 from an inlet opening 49 thereof disposed adjacent the closed end 41 will pass out through the outlet 40 and impinge against an internally arcuate wall 50 of the member 42 and be redirected tothe slits 47 and, thus, into the chamber 18 to charge the same in a manner hereinafter set forth, the closed end 46 could be provided with a diametrically located slit for this same purpose, if desired.

A coupling end or outlet member 51 of a tube means 52 leading from a pressure regulator structure 53 for a propellant source bottle 54 can have its cylindrical end 55 inserted into the larger section 39 of the opening 35 of the dispensing unit 32 in the manner illustrated in FIGS. 4 and 5 so that the needle-like member 37 will be received through a self sealing slit, hole or bore 56 in a sealing member 57 thereof and engage against a valve member plunger 58 as illustrated in FIG. 4 to move a valve member 59 away from its valve seat 60 of a valve unit 61 carried in the end member 51 as illustrated in FIG. 5 so that propellant passing from the propellant storage container 54 through the pressure regulator 53 and into the tube 52 can now pass through the opened valve unit 61 to a chamber 62 defined between the valve device 61 and the sealing member 57 and, from the chamber 62, into the inlet opening 49 of the needle-like member 37 and, thus, to the chamber 18 for pressurizing the liquid therein.

In this manner, the pressure regulator structure 53 of the propellant source bottle 54 will maintain the pressure of the propellant entering the chamber 18 of the dispensing container 10 at a predetermined pressure level that is satisfactory for dispensing the particular liquid through the syphon tube 19 and dispensing unit 32 when the spigot 21 is opened by the handle 22 as previously described, the pressure regulator structure 53 not providing the claimed subject matter of this patent application but forming the claimed subject matter of applicants co-pending patent application Ser. No. 213,701 now US. Pat. No. 3,762,431.

Nevertheless, it can readily be seen that the needle- Iike member 37 of the dispensing unit 32 of the container construction 10 of this invention readily permits easy attachment of the outlet member 51 of the propellant storage tank 54 thereto as the same is located within the center of the large portion 39 of the stepped bore 35 so that the outlet member 51 will register the slit, hole or bore 56 of the sealing member 57 therewith The outlet member 51 is so constructed and interconnected to the tube 52 leading from the regulator 53 that the same simulates a pistol-like grip whereby the user can grasp the upper end of the tubular member 51 adjacent the outlet member 51 by wrapping his hand around the same and placing his thumb against the button-like end 51 of the member 51 to insert the same directly into the enlarged portion 39 of the bore 35 in a plug-in manner so that the needle-like member 37 is inserted in a needle-like manner into the end 55 of the member 51 to open the valve unit 61 in the manner previously described.

Since the valve member 59 of the valve unit 61 is normally biased to its closed position against the valve seat 60 by internal spring meansof the unit 61 in the same manner that such a valve unit is utilized in connection with an automobile tire, the outlet member 51 must remain in its fully inserted position within the opening 35 to maintain the valve member 59 in its open position relative to the valve seat 60, as illustrated in FIG. 5. Thus, the outlet member 51 has an outwardly directed tongue 52' extending therefrom one one side thereof which can be rotated beneath an outwardly directed tongue 23 on the plate member 23 in the manner illustrated in FIG. 5 after the tongue 52' has been abutted against the plate member 23 to indicate full insertion of the outlet member 51 within the bore 35 so that the valve unit 61 has been fully opened and by the subsequent rotation of the tongue 52' of the outlet member 51 under the tongue 23 of the dispensing unit 32, such fully inserted outlet member 51 will remain in this fully inserted position as illustrated in FIG. 5 until rotated from its interlocking relation with the dispensing unit 32 for removal from the opening 35 thereof.

Accordingly, it can be seen that the needle-like member 37 for the dispensing unit 32 acts in much the same manner as a football inflation needle for permitting the propellant to enter the chamber 18 of the dispensing container I0 and that the outlet end 51 for the propellant source 54 acts in much the same manner as the inflation valve means for an automobile tire in permitting the propellant from the storage tank 54 to be directed into the chamber 18 of the dispensing container 10.

Thus, the ultimate consumer can merely store the dispensing container in the position illustrated in FIG. 1 and attach the end 51 of the storage tank 56 thereto, as illustrated in FIG. I, so that the dispensing container 10 will remain fully and constantly charged with propellant for forcing the liquid therein through the spigot construction 21 when desired and when the particular container construction 10 has been emptied, the propellant storage tank 54 can be uncoupled therefrom and be utilized with a new dispensing container 10 for the same purposes.

As previously stated, one of the features of this invention is to provide means for fully supporting the container construction 10 in the horizontal dispensing position as illustrated in FIGS. 1 and 2 so that the container body 11 will not roll in its desired supporting position.

Accordingly, an annular collar 63 of this invention is carried by the container body 11 and, as illustrated in FIG. 3, has a first cylindrical portion 64 adapted to telescope onto the side wall 12 of the container body 11 at the front end 13 of the container body 11 while an inwardly directed annular flange 65 thereof is abutted against the end wall 13 to limit the telescoping of the collar 63 onto the container body 11 in the direction of left to right in FIG. 3. Such collar 63 can be press-fitted onto the container body 11, bayonet locked thereto or can be adhesively secured thereto as desired.

In any event, it can be seen that when the flange 65 is disposed against the front wall 13 of the container body 11, another portion 66 of thecollar 63 extends beyond the front wall 13 of the container body 11 so that a front annular, and beaded reinforcing edge 67 thereof projects beyond the dispensing unit 32 to tend to protect the dispensing unit from impacts and the like, at least from the sides thereof, as illustrated in FIGS. 2 and 3.

A lower portion 68 of the annular collar 63 is formed into a fluid drip trap configuration so as to have a flat bottom surface 69 for resting against a horizontally disposed supporting structure 70, as illustrated in FIG. 6, to prevent rolling of the container construction 10 when disposed in the dispensing position, as illustrated in FIG. 6. Such portion 68 of the annular collar 63 also has a recess 71 formed therein, as illustrated in FIG. I, so as to provide a liquid drip trap for any drippings from the spigot construction 21 during dispensing thereof so that such drippings from the spigot 21 will be caught in the trap 71 and not drip into the refrigerator normally receiving and storing the container construction 10.

The annular collar 63 has opposed openings or hand hold slots 72 formed therein so as to facilitate the grasping and carrying of the container construction 10. For example, a person can insert his hands respectively through the slots 72 to grasp the collar 63 and thereby carry the container construction 10. Also, as illustrated in FIG. 1, the tube 52 from the propellant container 54 can be passed through one of the openings 72 before being interconnected to the needle-like member 37 so as to be held by the collar 63 in an out of the way manner from in front of and below the spigot 21.

Such collars 63 for each container construction 10 also readily permit a plurality of container constructions 10 to be disposed in stacked, vertical, nested relation for storage purposes, transportation purposes and the like in the manner fully illustrated in FIG. 8.

In particular, it can readily be seen that each container construction 10 is adapted to have its bottom or rear end 14 telescoped down into the open end of the collar 63 of the container construction 10 disposed below the same until the annular shoulder 16 thereof abuts against the end edge 67 of the collar 63 of the lower container construction 10 so that such upper container construction 10 is now supported on the collar 63 of the lower container construction 10 in such a manner that the dispensing unit 32 of the lower container construction 10 is disposed in spaced relation from the concave end wall 14 of the upper container construction 10, as illustrated, whereby the collars 63 fully permit the vertical nesting of the container constructions 10 in a protective manner for the dispensing units 32 thereof.

Therefore, it can be seen that this invention not only provides an improved container construction having many novel, useful and unobvious features, but also this invention provides improved parts for such container construction.

While the dispensing units 32 of this invention have been illustrated as being utilized with a particular container body 11, it is to be understood that the dispensing units 32 of this invention can be utilized with other types of container bodies or the like.

For example, reference is now made to FIG. 9 werein another container construction of this invention is generally indicated by the reference numeral 10A and parts thereof similar to the container construction 10 are indicated by like reference numerals followed by the reference letter A.

As illustrated in FIG. 10A, the container body 11A has opposed ends 13A and MA with the dispensing unit 32A of this invention being disposed in the opening 25A of the wall 13A in the manner previously described. However, the container body llA formerly was utilized in connection with a propellant storage arrangement which was actually disposed within the container body 11A and inserted therein through an opening 73 in the wall 14A. For example, see the US. Pat. No. 3,243,085 to Wilson, for such an internal arrangement. I-Iowever,since the dispensing unit 32A of this invention can provide for an external source of a charging propellant to be interconnected thereto, the open ing 73 in the wall 14A of the container 11A can be suitably sealed closed by a bung 74 fitted therein and locked by a split ring 75, as illustrated.

Thus, formerly used container bodies 11A can be modified by the dispensing unit 32 of this invention to accept external propellant charging means at the needle-like member 37 thereof in the manner previously described.

However, it may be desirable to utilize other dispensing units for the container bodies 11A while still providing for external propellent charging of such container constructions 10A. Thus, the bung 74 for a container construction can carry a needle-like member 37A and one-way check valve structure 44A as illustrated to permit coupling to an outlet member '51 of a propellant storage tank 54 in the manner previously described. Also, the bung 74 can have the locking tabs or tongue 23'A to cooperate with the tongue 52' on the outlet member 51 for the reasons previously described. Of course, the container construction 10 can have the dispensing unit 32 of this invention as well as the bung 74 with the needle-like member 37A therefor to permit the user to select where the external propellant supply is to be interconnected thereto.

Therefore, while present preferred embodiments of the invention have been illustrated and described, it will be recognized that the invention may be otherwise variously embodied and practiced within the scope of the following claims.
